Connecting the charger improperly may cause serious damage to the device. Any damage caused by misuse is not covered by the warranty.

After fully charging, disconnect the device from the charger. First unplug the charger from the device, and then unplug it from the electric socket.
To save energy, unplug the charger when not in use. The charger does not have a power switch, so you must unplug the charger from the electric socket when not in use to avoid wasting power. The charger should remain close to the electric socket and easily accessible while charging.
